While upgrading to Windows 8, I am planning to still keep Windows 7 on my PC in a dual boot setup in case I need to fallback to Windows 7. Currently, Radmin on the Windows 7 instance in activated.

My question is can I activate the same license in both, Windows 8 and Windows 7 as its the same PC and only one of them would be running at a given time?

If not, would uninstalling Radmin from Windows 7 instance release the activation? So that I can then activate the Windows 8 instance without having to create a ticket for customer support to give me additional activations?
